- Retry actually retries: 'r' in the browse popup re-requests a
timed-out user (previously the 'Press b to retry' hint did nothing —
b wasn't handled inside the popup). BrowseTabs::retry_active is
unit-tested.
- Friendlier timeout copy that explains the likely cause: "Couldn't
reach <user>. They may be offline, or their connection can't be
reached (both of you may be behind a router/firewall). Press r to try
again."
- Replace protocol terminology in user-facing labels: 'Peer slots' ->
'Free slots', 'Peer upload speed' -> 'Upload speed'.
